Title: Geologic features and genesis of Langdonggou Au-Ag deposit,Baishan City of Jilin Province
Abstract: Langdonggou Au-Ag deposit is the second small ore deposit in Paleozoic depression.Through the analysis of the ore body shape,ore composition,structure,wall rock alteration,S isotopic determination and ore decrepitating method,it is considered that metallogenitic material derived from the ore-bearing rock body and the stratum;in lithogenesis and mineralization,magmatic syntexis and metasomatism are relative intense,The metallogenenic epochs can be divided into two one,and the metallogenic temperature can be divided into three stages.The study shows that Langdonggou Au-Ag deposit related to mesothermal shallow-seated magmatic hydrothermalism,which belongs to fissure filling vein Au-Ag deposit.
